To use all the features of the IDPA server, you must have a license file before deployment of the IDPA server.
You can activate the IDPA server using in-product activation or manual activation.
The in-product license activation enables the ACM to automatically download the licenses for Protection Storage, Backup Server, and Reporting and Analytics products from the ELMS server.
Note: Ensure that the appliance is connected to a network with a working Internet connection to automatically download the licenses.
After you download the licenses, the License tab on the IDPA Configuration page is not displayed. If the licenses are not downloaded successfully during the network configuration, the License tab is displayed on the IDPA Configuration page with a Check online for licenses button. You can click Check online for licenses to download the licenses from the ELMS server.
Note: If the system is unable to download the licenses automatically from the ELMS server, an error message displays, and you must manually activate the licenses.
